染色体数の違いと染色体進化の要因

 The complex interplay between chromosome, climatic niche and morphological traits shapes the diversification of Carex (Cyperaceae)

Ana Valdés-Florido , Joan Cuscó-Borràs , Santiago Martín-Bravo , Carmen Benítez-Benítez , José Ignacio Márquez-Corro , Modesto Luceño , Andrew L Hipp , Marcial Escudero

Annals of Botany mcaf290 (2025).
